Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present description as detailed in the accompanying claims.
The terminology used in the description presented herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used in this specification to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present description. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
In the running process of the existing network, if the current equipment fails, the existing networking scheme can quickly switch the flow to the standby equipment. However, if the device forwarding chip fails, that is, the corresponding link switching mechanism cannot sense that the device cannot forward the traffic actually, the corresponding traffic is always forwarded to the failed device, so that the current network fails.
In a VRRP networking as shown in fig. 1, if a link of a Network connected with a Master device fails, the VRRP protocol will elect another Backup device as the Master to forward the corresponding traffic. However, if the device as the Master has a chip problem, traffic is forwarded from the device as the Master on the VRRP, but in reality, the traffic is already discarded or blocked on the device, and the switching mechanism of the VRRP is not triggered, so that the entire networking environment fails.
As shown in fig. 2, each Monitor Link group is composed of two member interfaces, namely an uplink interface and a downlink interface, and one Monitor Link group can have a plurality of uplink interfaces or downlink interfaces, but one interface can only belong to one Monitor Link group.
The interfaces Port B1 and Port B2 of the Device B form a Monitor Link group, wherein Port B1 is an uplink interface, and the Link where the interface is located is an uplink Link; port B2 is a downlink interface, and the link where the interface is located is a downlink. The situation on Device D is also similar to Device B.
In the prior art, only the monitoring of the interface can be realized, namely, the downlink interface down is triggered when the uplink interface down, and whether the forwarding chip fails or not cannot be detected.
In order to solve the above technical problem, an embodiment of the present disclosure provides a method for protecting traffic, where the method is applied to any target routing device in an aggregated link, as shown in fig. 3, and the method includes:
s301, determining a monitoring port and a monitored port of the target routing equipment;
s302, enabling a monitoring function of the monitored port and the monitored port;
s303, acquiring a monitoring result, and if the transmission quality problem exists according to the monitoring result, disconnecting the downlink interface and/or the uplink interface of the target routing equipment.
In step S301, the administrator may configure an uplink interface of the target routing device as a monitored port, and configure a downlink interface of the target routing device as a monitored port. Or, the downlink interface of the target routing device is configured as a monitored port, and the uplink interface of the target routing device is configured as a monitored port. For example, an administrator may add a monitoring list, set a monitoring port and a monitored port in the monitoring list, and at the same time, configure an associated protocol for enabling a monitoring function, e.g., VRRP, S-trunk, static aggregation, etc., and set a threshold.
In this embodiment, before executing step S302, it may also be determined whether the target routing device is in the active state, if it is determined that the state of the target routing device is in the standby (Backup) state, step S302 is not executed, otherwise, the step is executed.
In this embodiment, the monitored traffic may be selected by setting up the modes such as uRPF, QOS, packet filtering, and MAC address selection, and if the uRPF fails to check, QOS limits, packet filtering, or the MAC of the traffic is not matched, and the table entry record of the destination IP has no route packet loss appears, the table is a configuration problem, the log is sent to the log server, the operation and maintenance is checked, and the flow is ended.
In this embodiment, a timer may be further set to implement periodic detection, and when the timer is started, the monitoring function of the monitoring port and the monitored port is enabled, and after the timer times out, a monitoring result is obtained.
In step S303, a ratio of a traffic rate of the uplink interface to a traffic rate of the downlink interface may be obtained, and when the ratio is smaller than a threshold value, it is determined that there is a transmission quality problem, and the downlink interface and/or the uplink interface of the target routing device are disconnected.
Meanwhile, if a plurality of downlink ports exist, a shorter timer (10 s) can be created, the plurality of downlink ports are polled (only one downlink port link is guaranteed to be normal at a time), the ratio of the flow rate of the uplink interface to the flow rate of the downlink port is queried for a plurality of times, if the ratio is smaller than a threshold value, an interface event is triggered, the downlink port link is disconnected, and a log is sent to a log server.
In one network shown in fig. 4, router a and Router B are dual-active access, and for a Switch, router a and Router B are a Router, and traffic load is shared between two devices. The upstream port (interface to left Internet), downstream port (port connected to Switch), protocol (static aggregation), timer (1 minute) and threshold (0.5) are simultaneously configured on Router a and Router B. At this time, if the Router a detects that the ratio of the flow rate of the uplink interface to the flow rate of the downlink interface is less than 0.5 (at this time, the chip is abnormal or fails), and no related error packet loss information is configured, the downlink is disconnected, so that the flow from the switch can only be sent from the Router B, and the recovery of the existing network failure is ensured.
According to the embodiments, the monitoring port and the monitored port are arranged, the flow ratio of the monitoring port and the monitored port is compared with the threshold value, so that whether the forwarding chip of the equipment has faults or not is judged, and if the faults exist, the link switching is performed.
Based on the above method embodiments, the present disclosure further provides a routing device, where the routing device includes:
the determining module is used for determining a self monitoring port and a monitored port;
the monitoring module is used for enabling the monitoring function of the monitored port and the monitored port;
and the processing module is used for acquiring a monitoring result, and disconnecting the downlink interface and/or the uplink interface of the target routing equipment if the transmission quality problem exists according to the monitoring result.
